Redefining the Shallow Mount Subwoofer

If you are in need of a shallow mount subwoofer, then look no further that the JL Audio 13TW5v2-2. This new and unique thin-line sub is going to give you the most sound out of the smallest space. The DMA-optimized motor system will produce a consistent motor force over a long range of strokes and power levels. U.S. Patented Floating Cone Attach Method (FCAM) aligns the cone and surround without depending on the spider and coil assembly, resulting in an improved pistonic motion. Even with all the advanced technology that JL Audio uses, the best feature is still its mounting depth. The 13TW5v2-2 only requires 2-5/8" inches of space to mount. You are only 2-1/2" away from the greatest sounding shallow mount subwoofer you have heard.

Subwoofer Specifications

Subwoofer Series

Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.

TW5 (JL Audio)

Subwoofer Size

Refers to the diameter of the subwoofer, measured in inches.

13.5"

Peak Power Handling

Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.

1200 watts

RMS Power Handling

The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.

600 watts

Voice Coil(s)

Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.

Single

Impedance (Per Voice Coil)

The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.

2 ohms

Frequency Response

The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).

20 - 200 Hz

Sensitivity

An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".

85.51 dB

Xmax (millimeters)

Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.

11 mm

Subwoofer Design

This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle

Main Cone Color

This is the color of the speaker's or subwoofer's cone.

Black

Woofer Composition

Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.

Mica Injected Polypropylene (MIPP)

Woofer Surround

A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.

Santoprene Rubber

Subwoofer Grille

Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.

Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.

No

Recommended Enclosure Specifications

Recommended Enclosure Type

This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Sealed

Minimum Sealed Box Volume

This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.

0.8 cubic feet

Maximum Sealed Box Volume

This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.

0.8 cubic feet

Top-Mount Depth

The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.

2-5/8"

Cutout Diameter

The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.

12-1/2"

Shallow Mount Installation

This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Yes

Electromechanical Parameters

Free-Air Resonance (Fs)

The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.

25.95 Hz

Equivalent Compliance (Vas)

This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.

64 liters

Total Speaker Q Value (Qts)

This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses.
Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.

0.479

Electrical Q Value (Qes)

The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.

.51

Electrical Resistance of Voice Coil (Re)

Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.

2.100 ohms

Mechanical Q Value (Qms)

This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 – 10.

This is a great shallow mount sub. I bought one and had a custom box made and put it in a single cab chevy facing downwards. It may not hit the lowest of the lows,but JL has done better than anyone else at making a shallow sub sound as if it is a deep mount. highly recommend this if your short on space
